Hmmmm, I'm sure you told me before but why did you order the radio delete? Didn't know that was a rare thing, of course ive never really thought about it.
I ordered the car and was big into car audio back then, still am to a degree. I just didn't want to pay for something I wasn't going to use. It still came with the antenna and all the wiring under the dash. They just slapped in a blank face plate on the assembly line as opposed to plugging up the connectors and installing the factory radio.
That center section where the radio sits was smooth gloss black and had chrome trim instead of the gray trim. I practiced on the back side until I found the right grit sand paper to match the brushed texture as best as I could. I color matched the stock gray trim ring using black and gray modeling paint. It's a really close match to the factory brushed finish, which is 85 model specific.
Seems like I tried to buy a "replacement" face plate and either I thought it was too expensive or it was going to take a long time to come in - that was so long ago that I just can't remember - lol,
